This Common Core operations and algebraic thinking lesson covers how to solve subtraction word problems using several strategies. The lesson includes research-based strategies and strategic questions that prepare students for Common Core assessments. In this lesson, students are asked to write an equation that represents the word problem, and then asked to solve for the unknown number which can be a difference or one of the amounts. Other strategies include drawings with grouping and the number line. In addition to the lesson, there are four pages of Independent Practice with questions modeled after the Common Core assessment items.
